What is the ToolDeck online video cropper?

ToolDeck Video Cropper is a free, browser-based tool that crops a video to a new aspect ratio and frame. It runs on the ToolDeck multi-track video editor and uses WebCodecs and WebAssembly to crop and render on your own device, so your files are never uploaded to a server. It needs no account, adds no watermark and exports MP4 up to 4K at 60 fps.

It is best for social videos, vertical and square formats, removing black bars and tightening a shot. It does not track subjects automatically, and framing is visual rather than a pixel-exact crop box. Because it is built on the full editor, you can also trim, caption and add music in the same session.

Crop, trim and resize: what is the difference?

Crop video
Remove the outer edges of the picture so the frame has a new shape or a tighter subject. Duration stays the same.
Trim video
Cut time from the start or end of a clip. The picture is not changed. Video Trimmer.
Resize video
Change the pixel dimensions of the whole picture, for example 1080p to 720p, without removing any of it.
Change aspect ratio
Change the shape of the frame, for example 16:9 to 9:16. This is usually done by cropping, or by fitting the video inside the new frame with a background. Landscape to Vertical.

How to crop a video in 4 steps

  1. 1

    Import your video

    Drop an MP4, WebM, MOV or MKV file into the editor above. It opens in your browser and is not uploaded.

  2. 2

    Choose the aspect ratio

    Open the Ratio menu and pick 9:16, 1:1, 4:5, 16:9 or another shape. The preview updates at once.

  3. 3

    Frame your shot

    Select the clip, then scale and move it so the part you want to keep sits inside the frame. Turn on Blurred background if you want to keep the full picture.

  4. 4

    Export the cropped video

    Choose resolution and frame rate, pick GPU or CPU rendering and press Export. Download the MP4. It has no watermark.

What you get with this video cropper

  • Crop to any social ratio

    Choose 9:16, 1:1, 4:5, 16:9, 4:3, 3:4 or 21:9 in one click. The preview shows the new frame straight away so you can see what gets cut.

  • Frame the shot yourself

    Scale and move the clip inside the frame to keep the face, product or text you care about in view. Crop in tight or keep the full picture.

  • Blurred background option

    Do not want to lose any of the picture? Fit the whole clip inside a vertical or square frame and fill the empty space with a blurred copy of the video.

  • Crop, then keep editing

    This cropper runs on the full ToolDeck editor, so you can trim, add captions, text, filters and music after you crop, then export once.

  • Export up to 4K MP4

    Render H.264 MP4 at 720p, 1080p, 2K or 4K. The WebCodecs engine uses your graphics card when it can and your CPU when it cannot.

  • Private by design

    Cropping and rendering happen inside your browser tab. Your video is opened from your device and never sent to a ToolDeck server.

What you can do with a video cropper

  • Instagram Reels, TikTok and Shorts

    Crop a landscape clip to 9:16, keep the speaker centred and export a vertical MP4 ready to post.

  • Instagram feed posts

    Crop to 4:5 for the tallest feed post, or 1:1 for a clean square that also looks good in the grid.

  • Remove black bars

    Crop away letterbox or pillarbox bars so the picture fills the frame.

  • Cut out unwanted edges

    Crop out a stray object, a tripod leg, a timestamp area or an empty border at the edge of the shot.

  • Zoom in on the subject

    Crop tighter on a face, a product or a screen area for a closer, more focused shot.

  • Screen recordings and tutorials

    Crop a screen recording to just the app window or the part of the screen that matters.

Crop video online FAQ

Detailed answers about cropping, aspect ratios, quality, privacy, formats and limits.

Cropping basics

How do I crop a video online for free?

Drop your video into the ToolDeck editor above, open the Ratio menu and choose the shape you want, such as 9:16 or 1:1. Scale and move the clip so the part you want sits inside the frame, then press Export and download the MP4. It runs in your browser, so nothing is uploaded and the video has no watermark.

What is the difference between cropping, trimming and resizing a video?

Cropping removes the outer edges of the picture and changes the frame shape. Trimming cuts time from the start or end. Resizing changes the pixel dimensions of the whole picture without removing any of it. Changing the aspect ratio, such as 16:9 to 9:16, is usually done by cropping or by fitting the video inside a new frame.

How do I crop a video to 9:16 for Reels, TikTok or Shorts?

Choose 9:16 in the Ratio menu. A landscape video will fill the tall frame only if you scale it up, which crops the sides. Move the clip so the speaker or subject stays centred. If you would rather keep the full picture, turn on Blurred background and the empty space is filled with a blurred copy of your video.

How do I crop a video to a square (1:1)?

Choose 1:1 in the Ratio menu and position the clip so the main subject is in the middle. Square video suits Instagram, Facebook and LinkedIn feeds.

How do I crop a video for Instagram?

Use 9:16 for Reels and Stories, 4:5 for the tallest feed post and 1:1 for a square post. Export at 1080p for sharp results.

Can I remove black bars from a video?

Yes. Pick the ratio that matches the real picture, then scale the clip until the black bars fall outside the frame. Check the preview to be sure no bar remains at the edges.

Free, watermark and sign-up

Is there a free video cropper with no watermark?

Yes. ToolDeck adds no watermark to cropped videos, needs no account and sets no credits or daily limit. The practical limits come from your device and a 1 GB size limit per imported file.

Do I need to sign up or install anything?

No. Open the page, drop in your video and start cropping. There is no login, no email wall and no download.

Does cropping reduce video quality?

Cropping removes pixels, so a tightly cropped video has fewer pixels than the original. Starting from a high-resolution source and exporting at 1080p keeps the result sharp. The editor does not add a watermark or extra compression beyond the export settings you choose.

Privacy and security

Is my video uploaded when I crop it?

No. Cropping and rendering happen inside your browser tab. To check, open the Network tab in your browser developer tools while you crop and export. The only downloads are the editor code.

Is it safe for private or client footage?

Your files are processed locally and never sent to ToolDeck servers, which makes it a good fit for private or client footage. Keep your browser updated and avoid shared computers for sensitive work.

Does it work offline?

After the page and editor code have loaded, cropping and rendering run locally and do not need the internet. Reloading the page while offline may not work unless your browser has cached it.

Formats, export and quality

What video formats can I crop?

You can import MP4, WebM, MOV and MKV files if your browser can play them. Export is MP4 with H.264 video and AAC audio in Chrome and Edge. The recorder engine exports MP4 or WebM depending on the browser.

What is the maximum export resolution?

Up to 4K at 60 fps if your device has enough memory and processing power. For most social videos, 1080p at 30 fps is faster and plenty sharp.

What is the maximum video length and file size?

Each imported file can be up to 1 GB. Projects of a few minutes work best. Very long videos can run out of browser memory, so split them into parts.

Does the cropped video keep its audio?

Yes. The audio of your clip is kept and exported with the video. You can also mute it, fade it, detach it or add music in the same editor.

Why is my export slow, or why does the tab crash?

Usually the browser is short of memory or processing power. Close other tabs, export at 1080p and 30 fps, trim big source files first, or split a long video into parts. Chrome or Edge on desktop is the most reliable.

Features and limits

Can I add captions or text after cropping?

Yes. The cropper runs on the full ToolDeck video editor, so you can add AI captions, text, filters, transitions and music after you set the frame, then export once.

Does it track the subject automatically?

No. There is no AI auto-reframe or subject tracking. You frame the shot yourself. If the subject moves a lot, split the clip and reframe each part, or use the blurred background option to keep everything in view.

Can I enter exact pixel values for the crop?

Framing is visual: you choose an aspect ratio and then scale and move the clip. This suits social video. It is not a pixel-exact crop box tool.

Which browser works best?

Chrome and Edge on desktop give the best results because they support WebCodecs for fast GPU or CPU export. Firefox works with the compatibility engine. Safari has limited support for some canvas features.

Does it work on iPhone and Android?

The editor loads on mobile, but the layout and performance are built for desktop. For serious cropping and exports use Chrome or Edge on a computer.

Legal and responsible use

Can I use cropped videos commercially?

ToolDeck adds no watermark and claims no rights over your exports. Whether you can use a video commercially depends on the rights to the footage, music and images inside it, so make sure you are licensed to use them. This is general information, not legal advice.

What this cropper does well, and where it is limited

Everything runs on your own computer, so results depend on your browser, memory and graphics card. Check this table before a big project.

Tips for cleaner crops

  • Crop to the final ratio first

    Pick the ratio before you add text or captions so they sit in the right place for the final frame.

  • Keep a safe margin

    On Reels, TikTok and Shorts the app interface covers the top and bottom of the screen. Keep faces and captions away from the edges.

  • Start from the highest quality source

    Cropping removes pixels. A 4K source cropped to 1080p vertical stays sharp, while a 720p source cropped tight can look soft.

  • Trim and compress around the crop

    Cut unused footage first so the editor uses less memory, and shrink the final file for sharing.

ToolDeck vs cloud video croppers

Cloud croppers upload your file and process it on their servers. ToolDeck trades cloud AI for privacy and no limits: nothing is uploaded and the export has no watermark. Choose by what your project needs.

General comparison. Individual products differ, and features, limits and pricing change.

Use media you have the right to edit

Only crop and publish footage, music and images you own or are licensed to use. Cropping out a watermark or credit from someone else's work does not give you the right to reuse it. You are responsible for how you use the result.
